    1. Preclinical Evaluation and Intraoperative Human Retinal Imaging With A High-Resolution Microscope-Integrated Spectral Domain Optical Coherence Tomography Device

      Preclinical Evaluation and Intraoperative Human Retinal Imaging With A High-Resolution Microscope-Integrated Spectral Domain Optical Coherence Tomography Device
      Purpose: The authors have recently developed a high-resolution microscope-integrated spectral domain optical coherence tomography (MIOCT) device designed to enable OCT acquisition simultaneous with surgical maneuvers. The purpose of this report is to describe translation of this device from preclinical testing into human intraoperative imaging. Methods: Before human imaging, surgical conditions were fully simulated for extensive preclinical MIOCT evaluation in a custom model eye system. Microscope-integrated spectral domain OCT images were ...

    2. Methods, systems and computer program products for distributed scanning for motion artifact reduction in optical coherence tomography

      Methods, systems and computer program products for distributed scanning for motion artifact reduction in optical coherence tomography
      Methods of reducing motion artifacts in Optical Coherence Tomography (OCT) include scanning a sample with a scan pattern to acquire OCT data at a plurality of data locations. The data locations are distributed in the scan pattern across the sample such that at least some spatially adjacent data locations are acquired non-sequentially in time. A profile of the sample corresponding to a sample surface or an aspect of an internal ...

    3. Systems and methods for surgical microscope and optical coherence tomography (OCT) imaging

      Systems and methods for surgical microscope and optical coherence tomography (OCT) imaging
      A surgical microscope assembly includes a microscope main objective and microscope imaging optics. The microscope main objective and microscope imaging optics define a viewing beam path that passes from a sample through the microscope main objective and the microscope imaging optics. The assembly includes an optical coherence tomography (OCT) unit having an illumination beam and a collection beam and a beamsplitter between the microscope main objective and the microscope imaging ...

    5. Visualization of Real-Time Intraoperative Maneuvers with a Microscope-Mounted Spectral Domain Optical Coherence Tomography System

      Visualization of Real-Time Intraoperative Maneuvers with a Microscope-Mounted Spectral Domain Optical Coherence Tomography System
      The advent of optical coherence tomography (OCT) has revolutionized our diagnostic and therapeutic capabilities in ophthalmology and vitroretinal disease. In the clinic setting, OCT has touch nearly every aspect of vitreoretinal disease. More recently, OCT has been introduced into the operating room theater. Intraoperative OCT (iOCT) has been uses successfully...

    6. Efficient sweep buffering in swept source optical coherence tomography using a fast optical switch

      Efficient sweep buffering in swept source optical coherence tomography using a fast optical switch
      We describe a novel buffering technique for increasing the A-scan rate of swept source optical coherence tomography (SSOCT) systems employing low duty cycle swept source lasers. This technique differs from previously reported buffering techniques in that it employs a fast optical switch, capable of switching in 60 ns, instead of a fused fiber coupler at the end of the buffering stage, and is therefore appreciably more power efficient. The use ...

    7. Development of Extended-Depth Swept Source Optical Coherence Tomography for Applications in Ophthalmic Imaging of the Anterior and Posterior Eye (Thesis)

      Development of Extended-Depth Swept Source Optical Coherence Tomography for Applications in Ophthalmic Imaging of the Anterior and Posterior Eye (Thesis)
      Optical coherence tomography (OCT) is a non-invasive optical imaging modality that provides micron-scale resolution of tissue micro-structure over depth ranges of several millimeters. This imaging technique has had a profound effect on the field of ophthalmology, wherein it has become the standard of care for the diagnosis of many retinal pathologies. Applications of OCT in the anterior eye, as well as for imaging of coronary arteries and the gastro-intestinal tract ...

    8. Distributed scanning volumetric SDOCT for motion corrected corneal biometry

      Distributed scanning volumetric SDOCT for motion corrected corneal biometry
      We present a method, termed distributed scanning OCT (DSOCT), which reduces the effects of patient motion on corneal biometry utilizing current-generation clinically available spectral domain optical coherence tomography (SDOCT) systems. We first performed a pilot study of the power spectrum of normal patient axial eye motion based on repeated (M-mode) SDOCT. Using DSOCT to reduce the effects of patient motion, we conducted a preliminary patient study comparing the measured anterior ...

      Imaging And Visualization Systems, Instruments, And Methods Using Optical Coherence Tomography
      Imaging and visualization systems, instruments, and methods using optical coherence tomography (OCT) are disclosed. A method for OCT image capture includes determining a location of a feature of interest within an operative field. The method also includes determining a relative positioning between the feature of interest and an OCT scan location. Further, the method includes controlling capture of an OCT image at a set position relative to the feature of ...

      Corneal biometry from volumetric SDOCT and comparison with existing clinical modalities
      We present a comparison of corneal biometric values from dense volumetric spectral domain optical coherence tomography (SDOCT) scans to reference values in both phantoms and clinical subjects. We also present a new optically based “keratometric equivalent power” formula for SDOCT that eliminates previously described discrepancies between corneal power form SDOCT and existing clinical modalities. Phantom objects of varying radii of curvature and corneas of normal subjects were imaged with a ...

    13. Dual-depth SSOCT for simultaneous complex resolved anterior segment and conventional retinal imaging

      Dual-depth SSOCT for simultaneous complex resolved anterior segment and conventional retinal imaging
      We present a novel optical coherence tomography (OCT) system design that employs coherence revival-based heterodyning and polarization encoding to simultaneously image the ocular anterior segment and the retina. Coherence revival heterodyning allows for multiple depths within a sample to be simultaneously imaged and frequency encoded by carefully controlling the optical pathlength of each sample path. A polarization-encoded sample arm was used to direct orthogonal polarizations to the anterior segment and ...
